Radiator



Patented Apr. 15, 1930 UNITED STATES HARRY B. DE LONG, OF SPOKANE,WASHINGTON RADIATOR i Application filed June 20,

My present invention relates to improvements in radiators of the type employed especially in heating systems employing steam and hot water, and the device may also be employed in connection with refrigerators and other similar appliances.

As herein described and illustrated, I shall refer to the device as embodied in a radiator employed in a steam heating system for a dwelling, and the invention is particularly designed for the purpose of economizing in material and labor used in the installation of the heating system, as well as for the purpose of increasing the efiiciency of the steam radiator.

By the utilization of my invention, both the inlet pipe for live steam and the outlet pipe or drain for condensation are located at the same end of the radiator, and pass through openings in the floor which may conveniently be located and marked. By this arrangement of the device the radiator may be conveniently located, and the end of the radiator without pipes may be placed close against a wall, thus economizing in floor space.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully pointed out 3 and claimed. In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention Figure 1 is a view showing a steam radiator in side elevation and the pipes connected thereto;

Fig. 2 is an enlarged broken sectional vievi at the top of the radiator;

Fig. 3 is a sectional view at the top of the radiator showing the location of the steam pipe within the radiator;

Fig. 1 is a perspective view showing one end of the interior steam pipe; and

Fig. 5 is a sectional view as at line 55 in Fig. 3.

In Fig. 1, in order that the general arrangement of parts may readily be under- 1927. Serial No. 199,995.

stood, I have designated a floor 1 and ceiling 2 beneath the floor, and the radiator as a whole which is "designated by the numeral 3 is made up of two sections 1 and 5. The sections are composed of the usual tubes for the passage of steam from which theheat is radiated, and the radiator is provided with the usual feet 6, 6. p

The inlet pipe 7 supplies live steam for the radiator, and the steam passes through the usual valve 8, and this valve is provided with a pipe 9 that is threaded into a nipple 10, and the latter is provided with a bushing 11 which is threaded into an openingnear the top of the radiator section 4. The nipple 10 has interior threads for the pipe 9 and the bushing 11 has exterior threads to go into the opening in the radiator section 4:. Within this bushing. the steam pipe 12 is supported, and a second bushing 13 with exterior threads is located in openings in the adjoining walls of the radiator sections 4 and 5 as seen in Fig. 3. The steam pipe 12 passes through this bushing 13, and the bushing 13 as well as bushing 11, has a pair of ribs or flanges 14: for contact with the exterior face of the steam pipe 12. The end of the pipe 12 in the bushing 11 fits closely against the end of the pipe 9 in the nipple 10, and the ribs 14; in the bushing 13 provide a support for the steam pipe 12 and yet leave the bushing open for communication between the two sections 41 and 5. As best seen in Figure 4, the steam pipe, at one end, is cut away at opposite sides to form tapered tongues 15, 15, and betweenthese tongues an opening 16 is formed, which opening provides lateral ports that extend backwardly some distance from the end of this pipe 12. In this manner, the end of the pipe is supported in a bushing 17 of a plug 18, on ribs 19, and this construction leaves the end of the steam pipe open for emission of steam therefrom into the radiator section 5. Thus it will be seen that the steam is introduced to the upper right hand corner of the section 5 of thev radiator through the opening 16 of the steam pipe 12 to the interior of the section 5, and the steam is then distributed throughout the interior of the radiator sections. The condensation from the steam finds its way to the what I c lower left hand corner of the radiator in Fig. 1, and passes out through the connection 20 and thence throu h the drain pipe 21, the latter extending down through the floor as shown in Fig. 1.

At the right lower end of the radiator in Fig. 1 a plug 22 is shown which corresponds with the coupling 20, and it will be apparent that the pipes 7 and 21 may, if desired, be connected at the right end of the radiator in F i 1, in which event the openings at the left en would be closed in manner similar to the closing of the openings at the right end in Fig. 1, as shown.

It will be understood that the steam pipe 12 is not'rigidly connected at either end or its center to the radiator, but rests upon the l s or flanges 1 1 and 19 of the bushings,

an of course the forked end of the steam pi is closed by the plug or cap 18 of the ra i ator.

In installing the heating system, it will be apparent that two holes may be drilled, side by side, through the floor and ceiling for the pipes 7 and 21, and these holes or openings ma accurately be located in proper place in or er to economize in both labor and material in the installation of this system. By having both the intake and outlet pipes at the same end of the radiator, it will be apparent that the opposite end of the radiator may be located close to a Wall thus economizing in floor space.

Havln 1 thus fully described my invention,

lain; as new and desire to secure by Letters Patent is The combination with a sectional radiator havin an inlet pi e connected to t-he top of an and section an an outlet pipe connected at the bottom of said section, of bushin s supported in the upper portion of the ra iator and spaced lugs insaid bushings, a steam pipesupported inv saidbushings and adapted to receive steam from. the inlet pipe, and said steam pipe having a pair of tapered end tongues supported by the lugs of one bushingfand lateral openings within the radiator for the emission of steam.

In testimony whereof I aflix m signature.
